Explain the principle of “differential gene expression” and how different genes are expressed in different cell types. Describe in detail the two main mechanisms of the transcriptional regulation of gene expression. If you were going to “design” a transcription factor with an unlimited number of protein domains, how would you design this transcription factor so that it could take care of all of the transciptional regulation/expression of the muscle gene myoD.

there has been numerous studies presented on dendrites and dendritic spines, because of their essential roles within a functional neurocircuit. First, describe and explain how dendrites and dendritic spines play a significant role in neurocognitive processing on a circuit level. Second, discuss in detail how dendrites and spines can reflect alterations of brain state in the following topics: (answer all of them)
a) During hormonal changes
b) During learning/memory
c) Social deprivation
